Diffuse radio emission from the Coma cluster of galaxies at decameter wavelengths

Abstract

A map of the diffuse halo, Coma C, is constructed on the basis of observations of the Coma Cluster at 34.5 MHz with a resolution of 26 X 40 arcmin. The position angle is 50 + or 10 deg, and the integrated flux is 60 + or - 11 Jy. An extended source is noted to the south of Coma A whose measured half-power widths are 30 X 40 arcmin. The position angle is 135 deg, and the integrated flux approximately 15 Jy at 34.5 MHz. It is suggested that this source also belongs to the Coma Cluster.
